Abstract
A surgical instrument and system for use in a knee joint replacement operation. The instrument has a main body fastenable to a tibial cutting block. A first stylus and second stylus are each mounted on and movable relative to the main body, and are elongate between a first end and a second end. The first ends each have a reference surface for contacting a tibial plateau of the tibia. A compensation element is attachable to one of the styluses and has a plug-in section and a contact surface. The first ends each have a complementary plug-in section configured for releasable connection to the plug-in section. The contact surface is configured—when the compensation element is attached to the respective stylus—for contacting the tibial plateau instead of the respective reference surface and is spaced apart from the respective reference surface by a thickness dimension.
